What SAR value is dangerous?

Cell phones and other wireless electronic devices emit radio frequency (RF) radiation, which is measured as Specific Absorption Rate (SAR). Unless a device is properly tested and certified, it is difficult to know a device’s SAR value. Knowing the SAR value is important, as higher exposure to RF radiation increases the risk of serious health disturbances. A SAR level of 1.6 watts/kilogram or higher is generally considered dangerous.

What is SAR Value?

SAR value, or Specific Absorption Rate, is a measure of the energy that is absorbed by a human body when exposed to a high-frequency electromagnetic field. It is typically used to measure the power output of mobile phones, Wi-Fi routers, and other wireless devices.

What is a Dangerous SAR Value?

When it comes to SAR values, the higher the number, the more dangerous it is. The Federal Communications Commission (FCC) has set the safety limit for SAR value at 1.6 watts per kilogram (W/kg). This means that any device that has a SAR value higher than 1.6 W/kg is considered to be potentially hazardous to human health.

How to Check the SAR Value of Your Device?

The SAR value of a device can usually be found on the manufacturer’s website, or in the user manual. If you cannot find the SAR value of your device, you can check it on the FCC website.

What are the Health Risks of High SAR Values?

The health risks associated with high SAR values are still being studied, but some experts believe that they could potentially lead to an increased risk of cancer and other serious health issues. In addition, long-term exposure to high SAR values can cause headaches, dizziness, fatigue, and other health problems.


In conclusion, it is important to be aware of the SAR value of the devices you use, and to make sure that it does not exceed the safety limit of 1.6 W/kg. High SAR values can have serious health consequences, and should be avoided whenever possible.
